MOF Coating Enhances the Ion Tolerance of Micromotors

Angewandte Chemie, EarlyView.
This work reported a novel method to significantly enhance the ion tolerance of EMNMs using a MOF coating via controllable heteroepitaxial growth, enabling effective motion in high‐salt environments and propulsion through biological tissues under 980 nm NIR light, with potential applications in targeted drug delivery.

Subarachnoid Hemorrhage due to Ruptured Spinal Artery Aneurysm: A Diagnostic Challenge

Case Reports in Neurology, 2020
Subarachnoid hemorrhage (SAH) due to a solitary spinal aneurysm is extremely rare. Early diagnosis of spinal SAH is challenging, particularly when the spinal cord has not been compressed.

Spinal Cord and Root Compression [PDF]

Medicine, 2000
Abstract Spinal cord and root compression is a common problem in all specialties. There are many possible classifications, based on location (extradural or intradural), disease type (congenital, acquired, inflammatory, infective, neoplastic, degenerative or traumatic) or timing of onset (acute or chronic). Syndromes used to describe different clinical

UTX Responds to Nanotopography to Suppress Macrophage Inflammatory Response by Remodeling H3K27me3 Modification

Advanced Science, EarlyView.
Compared with those on the pTi surface, macrophages on the TNTs surface present reduced myosin II contractility, which facilitates the nuclear translocation of the UTX. This reduction decreases the enrichment of the repressive H3K27me3 histone modification at the Abca1 gene locus, which promotes the transcription and protein expression of ABCA1 ...

Automatic Segmentation of the Spinal Cord Nerve Rootlets [PDF]

Imaging Neuroscience, 2 (2024) 1-14
Precise identification of spinal nerve rootlets is relevant to delineate spinal levels for the study of functional activity in the spinal cord. The goal of this study was to develop an automatic method for the semantic segmentation of spinal nerve rootlets from T2-weighted magnetic resonance imaging (MRI) scans. Images from two open-access MRI datasets

Astrocytic ET‐1 System Determines Microglia Phenotype Following Spinal Cord Injury

Advanced Science, EarlyView.
The study reveals that astrocytic ET‐1 system is solely activated by thrombin following SCI via RhoA/NF‐κB and MAPKs/NF‐κB signal pathway. The release of astrocytic ET‐1 drives microglia polarization toward M1 phenotype through YAP signaling via ETA and ETB receptors.

Prediction of risk of fracture in the tibia due to altered bone mineral density distribution resulting from disuse : a finite element study [PDF]

, 2014
The disuse-related bone loss that results from immobilisation following injury shares characteristics with osteoporosis in postmenopausal women and the aged, with decreases in bone mineral density (BMD) leading to weakening of the bone and increased risk
